MODAL PARAMETERS EXTRACTION USING WAVELETS
|
| |
|
Summary :
|
|
ABSTRACT. THIS WORK PROPOSES THE USE OF WAVELETS IN MODAL PARAMETERS IDENTIFICATION
OF VIBRATORY SYSTEMS. THE DEVELOPED METODOLOGY USES OPTIMIZATION TECHNIQUES AS A
ISMATCHING PURSUITLN ALGORITHM MODIFICATION. SIGNALS OBTAINED FROM SIMULATION OF A
VIBRATORY SYSTEM WITH ARTIFICIALLY ADDED NOISE AND FROM EXPERIMENTAL TESTS ARE USED TO
EVALUATE THE METHOD ROBUSTNESS, ACCURACY AND RELIABILITY. THE METHOD PERFORMANCE IS
COMPARED TO THE RUZZENE™S METHOD.
KEY WORDS: MODAL ANALYSIS, WAVELETS, OPTIMIZATION. |
